PAPER-FEEDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 600,844, dated MarchI5, 1898. Application filed February 27, 1897. Serial No. 625,346. (Nomodel.)

To aZZ whom it may concern.-

Be it known that 1, JOHN H. RUssELL, of Amsterdam, in the county ofMontgomery, in the State of New York, have invented new and usefulImprovements in Paper-Feeding Machines, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

My invention relates to paper-feeding machines; and the object is toprovide suitable and efficient means for automatically feeding thickpaper, as pasteboard or strawboard, to the folding apparatus ofpaper-boX-making machinery.

In the drawings hereto annexed and forming a part of this specification,Figure 1 is a side elevation of my improved paper-feeding machine. Fig.2 is an end view of the same, looking from right to left of Fig. 1.vFig. 3 is atop plan view of the machine. Fig. 4 is a sectional viewtaken on line no a: of Fig. 3. Fig. 5 is a detail view, and Fig. 6 is asectional view taken through the center of the cross-bar.

Referring specifically to the drawings, A is a table, having four legs aa and a a. Near one end of the table, below the surface and extendingtransversely across'the same, is the driving-shaft B. Mounted on thecenter of this shaft to turn with it is a large roll or cylinder 0,having a central peripheral groove therein for a small roller, to behereinafter referred to. The periphery of this roller extends slightlyabove the surfaceof the table and may be covered with felt.. Abovethe.

roll O is a smaller roller O, which has its ends fulcrumed in yieldingbearings working in brackets c a, mounted on the sides of the table. I)b are coil-springs above said bearings, and o c are adjusting-screwspassing through the brackets c c and bearing upon the springs toregulate the pressure of the roll 0 upon the paper passing between therolls 0 and O.

A sprocket-wheel D on the shaft B serves to drive the shaft at theproper speed, depending upon the speed of the folding apparatus. Anothersmaller sprocket-wheel E on the same shaft is connected by a chain Ewith a large sprocket-wheel F, keyed to a shaft F turning in bearingsadapted to slide in dovetailed grooves in a pair of rails G G,

secured at their endsto the legs of the table.

The chain connecting the sprocket-wheels E and F is loose or ofsufficient length to allow the shaft F to be moved a greater distancefrom the shaft E to accommodate longer sheets of paper or board whennecessary.

Mounted on the shaft F, near its center, are a pair of large narrowrollers H H, separated from each other. Theserollers extend aconsiderable distance above the top surface of the table and haveatdiametrically opposite points on their peripheries transverse inclinedribs d, which are stationary on the rollers, and back of theseadjustable ribs 6 are springs which serve to strike the edge of thepaper or board sheet as the rolls revolve and carry it forward betweenthe rollers O and C, which feed said sheet to the folding apparatus.(Not shown.) The rear end of the pile of paper-boards P is raised by therolls to an inclined position, and the stationary ribs d on the rollsserve to insure the catching of the adjustable ribs against the rearedge of the lower board even if it be somewhat warped, as it is liableto be. For instance, should the rear edge of the lower sheet be warpedthese inclined ribs 01 will tend to raise the depressed portion of theedge and to straighten it. By simply turning the adj llSiJlHg-SCIGWS f fmore or less the adjustable ribs may be moved toward or from theperiphery of the roll, de-

pending upon the thickness of the sheets of paper P.

In order to provide a smooth inclined surface for the paper, a frame I,having three parallel longitudinal plates joined together at their ends,is hinged below the surface of the table between the rolls H and (J andheld at the other end above the table by a screw 6, passing through thetable and bearing upon its lower side. By means of the screw theinclination of the frame I may be varied as desired. The large rolls H Hare moved toward and from the roll 0 by means of a screw J, connectedwith the shaftF between the rolls H H and passing through a cross-bar K,extending between the legs a. a and a wheel h on the screw fulcrumed insaid bar.

By locating the feeding-disks or large rolls' II II with theirperipheries extending above the point of contact of the feed-rollers andalso above the frame I the ribs 6 on the disks can easily catch the edgeof the lower sheet when in its inclined position on the frame. When thesheets are inclined with their rear edges raised, the lower sheet can bemoved more easily by the rolls H H, and this arrangement necessitatesthe raising of the peripheries of the large rolls.

L L are parallel side guides for the paper, mounted upon the top of thetable and adj ustable toward and from each other by means of atransverse screw-shaft M below the top of the table, said screw-shafthaving right and left thread-engaging studs mm, extending downward fromthe said guides. The studs m m pass through slots 2' i in the top of thetable. The screw-shaft M is turned by means of a small wheel n on theend of the shaft at one side of the table.

Between the roll 0 and the front ends of the guides L L is an uprightboard N, secured at its ends to the table. This board has its lower edgecut away to provide a passage for the lower sheet of paper when it itforced forward by the large rolls H H. Said board N is cut away toaccommodate the thickest sheets that may be fed, and in order that thispassage may be closed more or less I provide an adjustable sliding boardor gate R, which may be raised or lowered, as desired. Said gate slidesbetween two vertical ribs 1" r, secured to the board N. A screw jprojects from the gate through a small slot is in the board N, and uponthe end of the screw and bearing upon the opposite side of the board isa thumb-nut Z, which secures the gate in position. The lower end of thegate is beveled, as shown in Fig. 4, so that the sheet of paper may bemore easily passed through even if somewhat warped.

Directly below the board N, below the surface of the table butprojecting slightly above the same, is a small roller .9, fulcrumed insuitable bearings. This roller decreases the friction at thecommencement of the movement of the lower sheet of paper. Said roller .9is located in the groove in the center of the roll 0.

The sheets of paper to be fed are out to the same size and placed uponthe inclined frame of the table, with their front edges bearing againstthe gate R. The side guides are then moved together to hold the sheetsin place loosely. The rolls H H are moved so that the shaft F isdirectly below the rear edges of the sheets P. When in operation, therolls H H will catch and carry successively the lower sheet to andbetween the rolls 0 and C, and these rolls carry the sheets to thefolder of the box-making machine. Small rollers may be set in the platesof the frame I to decrease friction.

In a paper-feeding machine, thecombination with the table and the guides, of horizontal feed-rollersbetween which the sheet is passed, large rolls having catches ondiametrically opposite sides, said rolls having their peripheriesextending above the point of contact of the feed-rollers, and means tomove the large rolls toward and from the feed-rollers, substantially asdescribed.
